显微组分对煤粉燃烧性和输送性的影响

Maceral Affected to Combustion and Conveying of Pulverized Coal

通过显微组分、燃烧性和输送性测定实验,研究了显微组分对煤粉的燃烧性和输送性的影响。试验结果表明:煤粉中过高的镜质组含量不利于煤粉燃烧过程和输送性能的改善,适当提高煤粉中丝质组、壳质组的含量有利于改善煤粉的燃烧性能和输送性能。

With the measuring experiments on the coal maceral,combustion and conveying,the paper study the maceral affected to the pulverized coal combustion and conveying.The experiment results showed that the vitrinite content too higher in the pulverized coal would not be favorable to improve the pulverized coal combustion process and the conveying performances.To appropriately increase the inertinite content and the exinite content in the pulverized coal could be favorable to improve the combustion and conveying performances of the pulverized coal.
